Load output inrush current HW fix availability for Bluesolar 75/15

Hello @mvader (Victron Energy),

I'm wondering whether your HW fix for the issue "smartsolar 100/20 load switches off in float mode" and other loads is already available today in the BlueSolar 75/15 series design?

Documented by "mvader" in

Mar 02 um 9:39 PM:

Here are the serial numbers per when the (hardware) change was implemented:

  • SCC075010060R SmartSolar MPPT 75/10 Retail HQ1935
  • SCC075015060R SmartSolar MPPT 75/15 Retail HQ1935
  • SCC110015060R SmartSolar MPPT 100/15 Retail HQ1947
  • SCC110020060R SmartSolar MPPT 100/20 Retail HQ1911

The 100/20 that we currently ship from our warehouses has the improvement. As do the 75/10 and the 75/15. The 100/15 is still shipping with hardware from prior to this improvement, due to stock levels of older production batches.


Has my two week earlier bought (from Offgridtec) BlueSolar 75/15 (+ BT dongle) with serial nummer (pls. see below) also fixed this BD35 compressor inrush current issue yet (that I highly rely on) or do I need to replace this device with which SmartSolar charger instead or when will it be available?

Many thanks in advance for your help and BR!

Victron confirmed to my distributor today, that my serial number which is starting with HQYYWW = HQ1933 was from a 2019 badge in calendar week 33 but they oviously mixed between the Bluesolar 75/15 (SCC010015050R) and Smartsolar 75/15 (SCC075015060R) devices as not any Bluesolar device was mentioned in the above list of @mvader (Victron Energy).

So all my answers regarding only the Bluesolar series design are still open.

Thank you much in advance for any help that is still highly appreciated!
